The DielsâAlder reaction of sulfoxide 2 with 1,3-dienes in CH2Cl2 afforded the corresponding CF3-containing mono- and polycycloadducts. In the case of the reaction of sulfoxide 2 and sulfonium salt 10 with cyclopentadiene, a mixture of four diastereomers was formed. The rotational potential energy surface (PES) of reagents 2, 10 was calculated and gave three minimum energy conformations with SO, Ph or the lone pair synperiplanar to the carbonâcarbon double bond.
